To all fio/0m t may concern.'

Be it known that I, CHARLES NAGY, a citizen ofA the United States, residing at llVar, in the county of McDowell and State of vWest Virginia, have invented certain new and useful Improvements in Rail or -Bar Bending' Implements, of which the following is a speciiication. Y

This invention relates to an implement for use in bendingtrack rails'or heavy rods or bars generally, and may be used either to bend such rails, rods or bars to a desired shape, or to straighten them when bent.

rIhe invention has for an obj ect to provide novel and improved implement of this type capable of exerting a high degree of force and whose moment of leverage may be varied according to the work to be done.

For further comprehension of the invention, and of the Vobjects and advantages thereof, references will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Figure 1 of the drawings is a face view of a rail bending implement constructed ac cording to my invention;

Fig. 2 is a longitudinal sectional view taken on the line 2-2 of Fig. 1; and

Fig. 3 is a fragmentary central longitudinal sectional view.

In constructing my improved bending implement I provide a frame element in theY form of a V-shaped yoke 10. rI`lie legs of the yoke are formed at their ends with suitably shaped parts adapted to engage the object to be bent. These ends are here in the form of block-like members 11 in which are T-slots 12 suitably shaped to engage the treadL and web of a rail 13, the slots in the respective ends being in substantial alinement with one another. As shown in Fig. 1

these slots are ilared, or increased in. width, Y e from the centre thereof toward their ends to permit of the lateral movement of the rail in the slots which takes place as the rail is being bent.

At the apex of the yoke a circular head 15 is formed and serves to adjustably support a screw 16. The outer end of this screw 16 is provided with a head 17 formed with a transverse aperture 18, this aperture being adapted to receive a rod or bar by which the i screw is turned.

The inner end of thescrewhas rotatably Y mounted thereon an abutment block adapted to bear on the rail13 midway 'between the points where it is gripped by the members 11. This abutment block is made upl of two' halves or 'sections 2O and 21 joined together along the median line of the screw by means of bolts 22, the 'unthreaded end. of the screw projecting into a [suitable recess `formed partly in each block section, an enlarged,

collar or liange 23 on lthe end of the screw holding it against longitudinal displacement from the block. One of the sections, 20 is formed with a nose 20 which overlies the end of the other section and is adapted to bear on the web of the rail. To take strain oli" the bolts 22 the contact-ingV faces of the sections 2O and 21 may vbe corrugated as r In the use of my improved bending implenient asv above described, the yoke ends 11 are engaged over the rail 13,'a suitable rod or bar is inserted in the hole V18 in screw head 17, Aand the screw 16 turned to cause the nose 20 to bear on" the rail. Y Y Y As shown in detail in Fig. 3, I havev prov vided a means whereby the leverage obtained may be'varied according as the object to be bent oers greater or lesser resistance to bending. To this end the yoke 10 has an exteriorly and interiorlyv threaded nut 30 screwed through the apex thereof, the eX-V terior threads being relatively line, the screw 16 being threaded through the nut. rIhis screw is formed with a second transverse aperture 31 a shortdistance from its head 17.l

At the outer end ofthe nut 30 is an en-A largedvhead 33 having' a pair of diametrically opposed longitudinal grooves 34: in its periphery. Into these grooves project the ends of screws 35 threaded through lugs 36 formed on the yoke 10. These screws serve to prevent rotation of the nut. Extending diametrically across the outerend face of the nut is a groove 37 which registers at its ends with the grooves 34.

If the object worked on canbebent relatively easily, the screws 35 are engaged in the grooves 34 and the screw 16 turned in the nut 30. If 'the object, however, oifers considerable resistance to bending the screws 35 are withdrawn from the grooves 34, the screws 16 turned in the nut until its aperture 31 registers with the groove 37 and a suitable turning bar or rod 88 inserted along said groove and through said aperture, the screw 16 and nut 30 thus turning as a single unit and a higher leverage being obtained7 as will be apparent.

Having thus described my invention what I claim as new and desire to protect by Letters Patentv of the United States is as follows?- 1. A bending implement comprising a yoke frame adapted to engage the article to be bent at opposite ends of said frame, and ascrew threaded through said frame and adapted tobear on the article between the said ends of the frame, and an abutment headV rotatably mounted on the end of said screw said abutment head comprising a pair of sections engaging in a plane lying in the screw axis, one of said sections havingan abutment nose overlapping the end of the other section the contacting faces of Said sections having interlocking corrugations formed thereon. Y'

2. A bending implement comprising a yoke frame adapted to engage the article to be bent at opposite ends of said frame, a nut threaded through said frame and having diametrically opposed longitudinal grooves cHAnLEs Nasr.
